Log Message:
jansson: updated to 2.11

Version 2.11

* New features:
  - Add json_pack() format specifiers s*, o* and O* for values that
    can be omitted if null
  - Add json_error_code() to retrieve numeric error codes
  - Enable thread safety for json_dump() on all systems.  Enable thread
    safe json_decref() and json_incref() for modern compilers
  - Add json_sprintf() and json_vsprintf()
* Bug Fixes:
  - Fix incorrect report of success from json_dump_file() when an error
    is returned by fclose()
  - Make json_equal() const-correct
  - Fix incomplete stealing of references by json_pack()
* Build:
  - Work around gcc's -Wimplicit-fallthrough.
  - Fix CMake detection of sys/types.h header
  - Fix jansson.pc generated by CMake to be more consistent with the one
    generated using GNU Autotools
* Other:
  - Miscellaneous documentation fixes
  - Remove unnecessary reference actions from parsers

Version 2.10

* New features:
  - Add JSON_EMBED encoding flag allowing arrays and objects to be encoded
    into existing streams
  - Add json_dumpb() function for dumping to a pre-allocated buffer
  - Add json_dumpfd() and json_loadfd() functions for dumping to streaming
    file descriptors
  - Add support for parsing buffers larger than 2GB
* Build:
  - Fix CMake build when LONG_LONG_INT is defined as ""
* Other:
  - Internal code cleanup

Version 2.9

* New features:
  - Add json_auto_t to automatically decref a value that goes out
    of scope. Available only on GCC and Clang.
* Build:
  - Fix CMake build (at least on Linux) by removing conflicting
    jansson_config.h from the distribution
  - Change CMake install target generation to be optional
* Documentation:
  - Small documentation fixes.

Version 2.8

* New features:
  - Always preserve insertion order of object items.
    json_object_iter() and friends, json_object_foreach() and
    json_dumps() and friends now always work in the insertion order of
    object items
  - Add json_object_foreach_safe() macro that allows
    json_object_del() calls during iteration
  - Add json_get_alloc_funcs() to allow reading the allocation
    functions set by json_set_alloc_funcs()
  - Add json_pack() format specifiers s?, o? and O? for values that
    can be null
* Bug fixes:
  - Fix a crash when parsing inputs consisting of very deeply nested
    arrays or objects
  - Never convert numbers to integers in the parser when
    JSON_DECODE_INT_AS_REAL is set. This fixes error messages for
    overflowing numbers when JSON_DECODE_INT_AS_REAL is set
  - Fix a use-after-free in json_pack() error handling.
  - Fix subnormal number parsing on mingw32.
  - Handle out-of-memory situations gracefully in the hashtable
    implementation
* Build:
  - Fix build with CMake on all versions of Visual Studio up to 2015
  - Fix pkgconfig libdir when using CMake
  - Fix CMake config for static CRT builds on Windows
  - Fix warnings on LLVM 6.0 targeting iOS arm64
  - Add coverlls.io support via Travis for a nice test coverage badge
  - Don't expect jansson_config.h to be in the compiler's include
    path
  - Add a build-time option to set initial hashtable size
  - Use snprintf and strncpy in place of sprintf and strcpy to silence
    linker warnings on OpenBSD
* Documentation:
  - Fix various typos in documentation, and a broken link
  - Add an example program in examples/
  - Fix building of documentation man pages
  - Document the fact that copying objects doesn't preserve the
    insertion order of keys
* Tests:
  - Don't use the nonstandard __FUNCTION__ macro in tests.
  - Use expr instead of $((...)) in shell scripts for Solaris 10
    compatibility.
  - Disable Visual Studio warning C4756 when triggered deliberately in
    tests
  - Other minor fixes
* Other changes:
  - List all unrecognized object keys when strict unpacking fails
  - Alter the order of the members of the hashtable_pair struct for
    easier debugging.
  - Minor performance improvement to json_dump() and friends
  - Minor style fixes
